Sarah Kemp's wait for a maiden LPGA title continues after the Australian finished fourth behind tournament winner Wei-Ling Hsu in Virginia at the Pure Silk Championship.
Hsu eagled the par-5 15th hole on Sunday, creating a four-shot swing that gave her a two-shot lead, as she went on to claim her first career victory.
She closed with a 3-under 68 to finish at 13-under 271, two shots clear of playing partner Moriya Jutanugarn.
Jutanugarn had a 70. Jessica Korda was third at 10 under after a 70.
Kemp, the half-way mark leader, bogeyed the last hole for a 70 to round out her best performance of the year.
Hsu’s eagle, aided by a fortuitous bounce that left her with a very makeable putt, came as Jutanugarn, who started the hole with a two-shot lead, drove into a bunker, needed two shots to get out, hit her approach to the edge of the green and three-putted for a double bogey.
And it all happened on the easiest hole on the course, again showing it can also be the decisive one.
The victory for the 26-year-old Hsu from Taiwan, in her 147th career start, was all but assured with another birdie on the par-4 16th that stretched her lead to three.
And it came on a sweltering day on the Kingsmill Resort's James River Course with parched fairways and greens that were fast and firm for all four rounds - unusual for May in Virginia.
The tournament, once among the most popular on the Tour, failed to attract several of the game's top players, perhaps because its purse of $1.3 million ($A1.7m) is third-smallest on the LPGA tour.
